STRIP-SHINGLE.

Specification of Letters Patent.

Patented Jan. 6, 1920.

Application filed October 18, 1918. Serial No. 258,703.

To all whom it may concern:

Be it known that I, HERBERT ABRAHAM, a citizen of the United States, residing at the city, county, and State of New York, have invented certain new and useful Improvements in Strip-Shingles, of which the following is a specification.

My inventionrelates to strip shingles of prepared roofing.

The principal object of the invention 1s to produce strip shingles of such form that a given area of roof deck can be covered and made watertight with a smaller quantity of material than has heretofore been required.

Another object is to produc a shingle strip having a plurality of nailin qcabs along its upper edge.

l A still further .object is to out the strips so that the cutaway portions of one row of shingles form the nailing tabs ofthe next lower row.

This invention pertains particularly to an improvement in strip shingles of the type shown and described in Patent No. 1,150,298, issued August. 17th, 1915, to F. (1. Overbury. lVith the shingle strip ofthat patent, having straight upper edges, it requires approximately 250 square feet of shingle surface to cover 100 square feet of roof deck, whereas with shingle strips made according to my invention, that is, having nailing tabs along their upper edges, the same area of roof deck can be covered and rendered watertight with approximately 200 square feet of shingle surface.

In the accompanying drawings,

Figure 1 is a plan view of a strip shingle embodying my invention;

Fig. 2 is a View of a fragment of a sheet of prepared roofing indicating the method of manufacturing the shingle strips;

gig. 3 is a section of land strip shingles an Fig. 4 is a modification showin shingle having semi-circular shaped ta 3.

According to my invention, I take a sheet of prepared roofing and cut out a plurality of smalloblong shaped openings 1 in rows across the sheet, the openings in any one row being disposed midway between the openings in the next upper and lower rows. In the completed strip shingles, shown in Figs. 1 and 4, these openin form the slits between adjacent shingles. he sheet is then a strip nailing severed along wavy-like lines 2, extending transversely along the sheet as shown in Fig. 2. This produces a multiple shingle strip having a series of nailing tabs 3 along its upper ed e, and having its lower edge formed 0 a series of straight lines extending parallel to the major-axis of the strip and separated by cut-out ortions which substantially correspond in s iape to the nailing tabs, said nailing tabs being disposed in staggered relation to the cut-out portions of the lower ed e. The strips are generally cut into bloc s of four shin les each, as indicated in Fig. 2, to form t e completed article shown in Figs. 1 and 4. It will be seen, by reference to Fig. 2, that the tabs 3 of any one strip are formed of material out out of the indentations of the next higher strip. In this way the shingle strips are produced without any loss of material other than that caused by the cutting out of the openings 1 and the necessary trnnming at the top and bottom of the sheet.

By varying the character of the cutting line 2 the tabs 3 may be made of other than triangular shape, for example, they may be of semi-circular shape, as shown in Fig. 4.

Having reference to Fig. 3, in which I have shown a section of strip shingles, laid in the. usual manner, that is with the shingles of one course covering the joints of the other, it will be seen that by provision of the nailin tabs 3 I effect a considerable saving of sfiingle material between nailing points over the old type of shin le strip having a straight upper edge; at t e same time the same amount of protection against leakage at the joints between adjacent strips is provided as with the old type of shingle stri vhm I claim is:

A multiple shingle-strip, having s aoed nailing tabs along its upper edge, an having its lower edge formed of a series of straight lines extending parallel to the major axis of the strip, with intervenin cutout portions corresponding substantia l in shape to the nailing tabs and dispose in staggered relation thereto, whereby, when the strips are laid as described, not more than two square feet of shingle material are required to waterproof each square foot of roof surface.

HERBERT ABRAHAM.
